When someone mentions “renewable energy,” what comes to mind? Solar panels on a roof? Biodiesel-powered cars? The term covers several technologies that could power the green economy of the future. However, one type of renewable energy is beginning to emerge as the best alternative to fossil fuels: wind power.
A 2007 report by the Global Wind Energy Council estimated that wind power generated 94 gigawatts of electricity worldwide, up from just 7.6 gigawatts in 1997. They project that by 2012, this number will be closer to 240 gigawatts.
